BYD Singapore International Marathon by Adidas 2026

Did you think you had tested the heat on a marathon? The French Riviera in July, Brazil, Australia? Adorable 😇. Welcome to Singapore, where mercury and humidity compete fiercely to see which one will bring you to your knees first 🥵.

The Singapore International Marathon, or SGIM for those in the know, is THE running event of an entire state. Not a region, not a metropolis among others: an island-state of 734 km² that, every first weekend of December, transforms into a giant urban circuit 🗺️. And it's been happening since 1982 📅. The history begins modestly, like any respectable major event. A handful of runners, a course, and tropical heat that already served as a natural filter. By 1984, more than 11,000 participants were answering the call: the machine was launched 🚀. In 1989, two local runners, Ricky Khoo and Toh So Liang, achieved victories that remain etched in national history. Singapore winning on its own asphalt is somewhat equivalent to a Frenchman on the podium of the Paris Marathon 🏆, except here, it's 28°C at 4 am 😅.

In December, it's the rainy season 🌧️, which can, in some years, add an extra layer of unpredictability on top of the baseline humidity. The nighttime temperature hovers around 26-28°C, with relative humidity often close to 90%. To give you an idea, it's like running in a steam room, but with cars 🚗 and illuminated signs displaying the intermediate times.

The real international recognition came in 2012: the marathon received the Gold Label from World Athletics, thus joining the very exclusive circle of races recognized at the highest level by the world athletics federation 🥇. Today, it is the only and unique Gold Label in Southeast Asia. A distinction that few marathons in the world can boast about. Covid hit in 2020, and the event adapted with a virtual edition ⌚️: Singaporeans ran from their neighborhoods, GPS firmly on their wrists, in the same heat 🌡️ but without the aid stations 🫣. The return to in-person in 2021 was welcomed as a liberation. Since then, participation has been growing: 55,000 runners in 2025, including 14,000 internationals from 80 countries 🌍. It is the largest race in the region, and no one comes here for a leisurely stroll.

Yes, you read that right. The marathon starts at 4:30 am ⏰. Not because the organizers are particularly sadistic night owls 🐦, but because running under the tropical sun of Singapore during the day would be a whole other discipline, probably called "survival" 🌞. The start takes place from the iconic F1 Pit Building, yes, the building that borders the Formula 1 circuit of Marina Bay 🏎️. Atmosphere guaranteed 💯. The course then runs through the arteries of the sleeping city, passing spots that make tourists dream and runners sweat 😮‍💨. On the agenda: the National Stadium 🏟️, the Esplanade (the famous "durian building" 🍈, referencing the local fruit whose iconic architecture leaves no one indifferent), the Marina bay with its skyscraper reflections on the water, Gardens by the Bay ⛲️ and its giant sci-fi-like trees 🌳, then a detour through East Coast Park along the seaside before returning to the Central Business District at sunrise 🌅. The finish line is in the historical district, between the Merlion, the half-lion half-fish creature symbolizing the city and colonial buildings.

The elevation gain? 215 meters positive over 42.195 km precisely 📐. That's not the enemy here. The enemy is the humidity level that reaches 80-90%, even in the middle of the night 🫣. In 2025, the men's winner, Ugandan Abel Boniface Sikowo 🇺🇬, completed the race in 2h15'40, more than 5 minutes above his personal record. For the women, Ethiopian Shuko Genemo won in 2h41'24, 20 minutes off her best time. These gaps are not calculation errors: they simply illustrate what Singaporean weather does to the world's best athletes 🌍.

The Singapore Marathon is a whole weekend of running spread over two to three days, with formats for all levels and ambitions 📆. The Marathon (42.195 km) is the royal distance, of course 👑. Starting at 4:30 am, reserved for organized pain enthusiasts and involuntary night owls 🌃. The Half Marathon (21.0975 km) offers the prestige of the SGIM without doubling the effort, same start time, same atmosphere, half the pavement 🙌. The 10 km is Saturday's accessible format, perfect for discovering the race and the monuments of the capital without leaving your locomotor abilities behind. And for families or beginners, the 5 km exists and deserves all the respect due 🫡. The Ekiden completes the picture: a marathon relay with 4 runners, one team, four segments, and a good excuse to share the suffering among friends 👯. Relay zones include Bayfront Plaza and Marina Barrage. For the youngest, the Kids Dash starts on Friday evening, because even children have the right to complain about the heat 👦. Finally, the cherry on top of the laksa (the local dish, don't try to translate 🍜): the Double Up Challenge, which allows running two different formats over the weekend. Every year, hundreds of daring participants rise to the challenge 🏆. The organization even holds a dedicated ranking to salute these people who perhaps made dodgy decisions but honored them to the end 👏.

The years pass, but the heart of this marathon remains intact: an entire city running, a high-level international format, and a heat that has never varied by a degree ❤️‍🩹.
